TSX ASZ401 Analog Output & Serial Communication Module

Product Description

The Schneider TSX ASZ401 is an analog output and serial communication module from the Modicon TSX Series 7 PLC family. It enables TSX PLCs to interface with external devices, including operator panels, printers, barcode readers, and other automation equipment, providing reliable and accurate signal transmission.

Moreover, the ASZ401 supports RS232C and RS422/RS485 serial standards, offering versatile connectivity across multiple industrial systems. Its electrical isolation safeguards the PLC backplane from voltage disturbances, while LED diagnostics simplify troubleshooting and system monitoring.

This module delivers high-performance analog output with four channels, supporting ±10 V and 0–10 V ranges with 11-bit resolution. Its short response time of 400 µs ensures rapid control of actuators and process equipment, while robust short-circuit protection ensures continuous industrial operation.

The TSX ASZ401 is a legacy module, discontinued but still widely deployed in existing TSX Series 7 installations. Schneider Electric recommends upgrading to M340/M580 platforms for long-term support.
